Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Referring to Fig. 1, this suspension type optical fiber composite insulator is made up of optical patchcord 1, glass fibre pultrusion insulation mandrel 3, suspension type aluminium alloy flange 6, silicon rubber umbrella cover 4, silicon rubber bonder layer 5, epoxide-resin glue bond layer 2.The surface of glass fibre pultrusion insulation mandrel 3 is provided with axial sulculus, its two ends are connected with suspension type aluminium alloy flange 6, optical patchcord 1 runs through the sulculus and the suspension type aluminium alloy flange 6 on insulation mandrel 3 surfaces, is provided with at the outside surface of insulation mandrel 3 and can satisfies the silicon rubber umbrella cover 4 that external insulation requires.Optical patchcord 1 adopts two ends to have standard fiber interface FC/PC, ST/PC or SC/PC series optical patchcord, when being connected, no longer need it to be carried out welding with expensive optical fiber splicer with the optical fiber of other equipment, connect easy to use, fibre loss is little, reliable operation.
The insulation mandrel 3 of the insulating body of this optical fiber composite insulator is a glass fibre pultrusion insulation mandrel, this plug adopts the glass fibre pulling to make through special process, have very high tensile strength (〉=600MPs), be about 2 times of common iron rod, for the 3-5 of high strength china doubly, the plug of employing 500mm diameter just can be made into mechanical load and reaches 100 tons composite insulator, for transmission line of electricity provides reliable product to UHV (ultra-high voltage), large-tonnage development; Should the rod core material also have favorable damping, creep resistance and fatigue crack-resistant simultaneously.Its structural drawing is as shown in Figure 2: the outside surface at insulation mandrel 3 has an axial square sulculus, and helicitic texture is processed into the part that flange 6 is connected in two ends.Purpose at its surface fluting is to be bonded in optical patchcord 1 usefulness silicon rubber bonder layer 5 in the sulculus, the thermal expansivity of the silicon rubber umbrella cover 4 of silicon rubber bonder 5, insulation mandrel 3 and insulating coating is approaching, between them, can not produce thermal stress like this, so little, the stable performance of the fibre loss of the optical fiber composite insulator of this structure; The purpose that is processed into helicitic texture in insulation mandrel 3 two ends and the junction of flange 6 is to be convenient to be connected with the flange at two ends, and this connected mode technology is simple, the reliable in mechanical performance of insulator.
Suspension type aluminium alloy flange 6, its structure as shown in Figure 3, side is provided with large and small shoulder hole within it; Macropore is threaded with insulation mandrel 3, and connects with the epoxide-resin glue bonding agent, and aperture penetrates optical patchcord; The outer end is provided with to hang uses the hole.This flange arrangement novelty connects solid and reliablely, and the upper surface aperture of this flange is to be used to draw optical patchcord 1, and optical patchcord from then on hole is drawn the back earlier with 5 sealing of silicon rubber bonder layer, and then seals with epoxide-resin glue bond layer 2; The lower end macropore of aluminium alloy flange is processed as threaded hole, is convenient to insulation mandrel 3 and connects.
The insulating coating of this optical fiber composite insulator adopts silicon rubber umbrella cover 4, and high molecular polymer silicon rubber has good hydrophobic nature and good ageing-resistant and etch resistant properties, has very high resistant lightning and presses.For example the 110kV composite insulator reaches 140kV at 0.6 milligram/square centimeter of equivalent salt density and close 1.0 milligrams/square centimeter (being equivalent to IV level and following filth) minimum pollution flashover voltages of ash, for the 3-4 of porcelain insulating substring under the equal conditions doubly.Even surface area is full filthy,, make filthy surface still have good hydrophobic nature because umbrella plate material has the effect of intermolecular migration, thereby it is used in the heavy pollution district, can prevent effectively that pollution flashover accident from taking place, and move the several years and need not clean, thereby effectively improve power supply reliability; Simultaneously umbrella disk also has good electrocorrosion-resisting performance, and behind 1000 hours electrolytic corrosion tests, any evidence of corrosion does not appear in its surface; The anti creepage trace test reaches 6-7kV, occupies international most advanced level; After the artificial accelerated aging test in 4000 hours, its machinery, electric property have no significant change.Silicon rubber umbrella cover 4 adopts that cover is sticking, die casting or liquid injection moulding is in the surface of glass fibre pultrusion insulation mandrel 3, and this structural manufacturing process is simple, dependable performance.
